In this manner thestrainer disk or plate C can be sealed against discharge of liquidtherethrough from the sink, tub or other liquid container through thedrain therefor.

In Figure 2 of the drawing the strainer disk I9 in contradistinction tobeing fiat or straight'has its center area depressed or of concavoconvexformation. To have the stopper or closure seal this type of strainerdisk or plate I9, it is necessary to depress the body III of the saidstopper or closure with the flange or rim I2 through contact with thesaid disk or plate becoming outwardly spread and effecting a sealedjoint between the latter and the said stopper or closure. Thisdepressing of the body I enables the hook terminal ll of the bail I5 tobecome latched with the plate or disk I9 on the passage of the sidemembers It of the said bail through selected perforations 20 in thisplate or disk I9 and in this manner anchorage of the stopper or closuretherewith is assured.

The bail I5 by being embedded in the rib I4 can be readily manipulateddirectly from. the said rib for the latching of the stopper or closureand also the unlatchingthereof and additionally this bail I5 reinforcesthe said rib.

The body Ill and the flange or rim I2 has the requisite yieldability orinherent elasticity for the successful fitting of the article to astrainer disk or plate and the easy removal of such article therefrom.The article when applied assures a perfect seal of the drain opening Bso that liquid Within a sink, tub or the like can not flow through thestrainer disk or plate into the drain opening B for the emptying of theliquid from the said sink, tub or the like.

What is claimed is:

An article of the kind described for use at a drain opening having aperforated strainer disk covering the same, comprising an imperforateresilient body for sealing the strainer disk when superimposed thereonand having a peripheral annular flange for contact with said disk at itsmargin, a rib formed with the body centrally of its uppermost side anddisposed crosswise a distance thereof for effecting a finger grip, ananchoring medium of inverted substantially U-shaped bail formation madefrom a single length of wire partially embedded centrally within thebody to have the intermediate portion reinforcing the rib with the tinesof the bail formation extended exteriorly of the body beyond its lowerface, and reversely extending laterally di: rected terminal hooks formedfrom said tines for insertion in selected perforations in said diskwhereby the flange will press against the said disk to have the body ina sealing condition about the said disk.
